limiting reactant and percent yield

The limiting reactant

• slows the reaction down
• is used up first
• is the reactant that is left over
• controls the speed of the reaction

Theoretical yield = 54g
Actual yield = 14g
Calculate the percent yield.

• 30.00%
• 40.50%
• 15.75%
• 25.93%

Theoretical yield = 1.98g
Actual yield = 0.92g
Calculate the percent yield.

• 30.25%
• 75.00%
• 58.12%
• 46.46%

I want to make a smoothie, To make one I need 1 orange, 2 strawberries and 1 mango. If I give you 5 oranges, 12 strawberries and 8 mangos how many smoothies can you make me?

• 5

• 10
• 8
• 4

Theoretical yield = 65.7g
Actual yield = 43.2g
Calculate the percent yield.

• 65.8%
• 58.5%
• 70.2%
• 75.0%

In the image, which reactant is limiting?

• The white molecules, because there are extra.

• The black atoms, because they are completely used up.

• The white molecules, because they are completely used up.
